Specification of Letters Patent.

A nnlication filed September 23. 1905. Serial No. 279,859.

My invention relates to a novel construe-1 tion in a device for or removing the cream from the top or nec portion of a milk-bottle, the object being to rovide a simple, efficient, and sanitary device of this character; and it consists in the features of construction and combinations of arts hereinafter fully described and claime In the accom anying drawings, illustrating my invention, Eigure 1 is a central longitudinal section of a'device constructed in accordance with my invention, showing the same in position on the bottle preparatory to removing the cream. Fig. 2 is a similar section, the tube being shown in elevation and the bulb. in its collapsed position. Y

My said device comprises a tube A, which is in the form of an inverted V, one of said arms being vertically disposed and the other thereof being shorter and disposed at an acute angle to form a delive -spout B. Between the ends of the vertica arm a substantially semispherical cup C is rigidly mounted, and disposed below the same is a rubber or small flexible fluid-tight bulb D, preferably spherical in form, said bulb being provided with diametrically opposite openings, one of other of which is of larger diameter than said tube, said larger opening being disposed at the lowest point.

My device operates as follows: After removing the' cap from the milk-bottle the tube A is inserted, and the bulb D rests upon the edge of the neck E of the bottle. The tube A is then moved vertically downward] so that the cup C bears'uponand gradu y collapses the said bulb D, thereby obviously ejecting the air, which latter passes into the bottle, and thus forces the li uid from the latter through the tube A and elivers' the same into any suitable receptacle from the spout B. The said cup!) is of less diameter than the largest diameter of said bulb D, so that in collapsing the latter by practically invert ing the upper half of said bulb the said cup will follow into the hollow thus formedthat is to say, the bulb becomes practically folded over the said cup and is t us readily practically completely collapsed and nearly all air contained therein ejected.- Durin downward movement of said tube A it is obvious that the liquid in theup er portion of the bottle only would be ej ecte as the lower or body portion woul be in no manner, disturbed by the operation, and thus the cream collecting in the u per end of the bottle would be ejected,w 'e the milk would remain.

, For the sake of convenience the said tube A may be provided at'its lower end with a prong F, by means of which the cap of the ottle may be primarily removed in a well- ,into the bottle, and a member disposed between the ends of said tube and rigid therewith adapted to bear upon and compress said bulb when said tube is moved downwardly substantially as and for the purpose described.

2. A device of the KJJld specified comprising) in combination, an inverted -V-shaped tu e one arm of which is adapted to enter a bottle or the like and the other arm of which constitutes a delivery-spout, a bulb disposed on said first-named arm ha an air-discharge opening in its lower end and adapted to rest upon the rim of the receptacle entered by said tube, and a member rigidly mounted upon said first-named arm and adapted to bear upon and collapse said bulb to discharge the contained airinto said receptacle when.

in in combination an invertedV -shaped Patented Jan. 8, 1907.

the

tu e one arm of which is adapted to enter a bottle or the like and the other arm ofwhicli constitutes a delive out, a substantially spherical rubber bul posed between the ends of said first-nained arm and adapted to rest upon the rim of the receptacle into which cup rigidly mounted upon and concentrical with said first-named arm, said cup being adapted to bear upon and collapse said bulb when said tube is moved downwardly.

4. A device of the kind specified comprising in combination an inverted-V-shaped tube one arm of which is adapted to enter a bottle or the like and the other arm of which constitutes a delivery-spout, a substantially spherical rubber bulb disposed between the ends of said first-"named arm and adapted to rest upon the rim of the receptacle into which the latter is inserted, said bulb having an air discharge opening communicating with said receptacle, and a substantially semispherical cup of smaller diameter than saidbulb rigidly mounted upon and concentric with said first-named arm, said cup bein adapted to bear upon and collapse said bu b when said tube is moved downwardly.

In testimony whereof I have signed my name in presence of two subscribing witnesses.
